A "triple bottom line" computer model developed for the Narragansett Bay watershed in Rhode Island will be adapted for use on Cape Cod.

Cape Cod Commission Executive Director Paul Niedzwiecki told the County Commissioners June 6 that the Environmental Protection Agency, which developed the model, agreed to "build us a model for use on the Cape."

It came in response to County Commissioner Bill Doherty of Harwich, who asked how to instill some level of urgency on the part of towns and residents with respect to wastewater.

Niedzwiecki said that the "triple bottom line" shows "the relationship between the environment, the economy and the people."

"That's exactly the discussion we need to have," Niedzwiecki said.

He said that is a predictive model that will show the effect on estuaries of decisions under different treatment scenarios.

The computer modeling developed by the Commission itself provides a more specific look, parcel-by-parcel, of different wastewater solutions and their costs.
